Beschreibung
Zusammenfassung:	Cartilage tissue and implants comprising cartilage tissue are produced in vitro starting from cells having the ability to form an extracellular cartilage matrix. Such cells are brought into a cell space (1) and are left in this cell space for producing an extracellular cartilage matrix. The cells are brought into the cell space to have a cell density of ca. 5x107 to 109 cells per cm3 of cell space. The cell space (1) is at least partly separated from a culture medium space (2) surrounding the cell space by a semi-permeable wall (3) or by an open-pore wall acting as convection barrier. The open-pore wall can be designed as a plate (7) made of a bone substitute material and constituting the bottom of the cell space (1). The cells settle on such a plate (7) and the cartilage tissue growing in the cell space (1) grows into pores or surface roughness of the plate, whereby an implant forms which consists of a bone substitute plate (7) and a cartilage layer covering the plate and whereby the two implant parts are connected to each other in positively engaged manner by being grown together.
